Abstract
The present invention is to utilize low temperature exhaust heat circulating generation, with absorption heat pump, electric drive pump coupled heat, using industrial exhaust heat as the power source of power generation, working medium after power generation enters absorption heat pump, drive absorption heat pump for working medium cooling by industrial exhaust heat, the high warm of acquisition obtains electric power for producing for heating.
Description
Technical field
The invention belongs to industrial afterheat recovery fields, are related to a kind of industrial afterheat recovery system of B-grade condensation.
Background technique
Country advocates waste heat recycling, clean energy resource heating, but most clean energy resource higher cost energetically, such as naturally
Gas, this kind of high-grade energy of electricity, being heated using this high-grade energy is significant wastage to the energy, and industrial exhaust heat is most
Valuable clean energy resource, because thermal temperature needed for heat supply is of less demanding, most industrial exhaust heat can all meet.And it is usual
Industrial afterheat recovery technology only high-temperature residual heat is recycled, low temperature exhaust heat still need it is cooling after can just be utilized, it is cooling
Waste heat also needs to consume part electric energy and water resource.
Summary of the invention
Problems solved by the invention is: utilize low temperature exhaust heat circulating generation, and absorption heat pump, electric drive pump coupled heat,
Using industrial exhaust heat as the power source of power generation, the working medium after power generation enters absorption heat pump and electric drive heat pump, passes through industry
Waste heat drives absorption heat pump, electric drive heat pump for working medium cooling, and the high warm of acquisition obtains electric power for giving birth to for heating
It produces.
The technical solution adopted by the present invention is that: the industrial afterheat recovery system of B-grade condensation includes: working medium generator, absorbs
Formula heat pump, compressor, evaporator, with hot family, electric drive heat pump, evaporator connects working medium generator, and the connection of working medium generator is inhaled
Receipts formula heat pump forms power generation major cycle, absorption heat pump high warm outlet connection electric drive heat pump, absorption heat pump low-temperature heat source
It is heat user heat supply that outlet connection evaporator, evaporator connect compressor, absorption heat pump and electric drive heat pump, which obtain heat source,；
Use absorption heat pump as level-one waste-heat recovery device in the major cycle, electric drive heat pump is as second level waste heat
Recyclable device, waste-heat recovery device are used as remaining heat-recovery condenser, and working medium generating set pumping driving absorption heat pump is done
It is transported to electric drive heat pump after work, as low-temperature heat source, is combined after doing manual work again with the Low Temperature Thermal of absorption heat pump discharge working medium
Evaporator is transported to as industrial exhaust heat cooling；
The compressor is started by external power supply, for working medium heating, is pressurizeed, after working medium generator drive, is generated electricity and connect
For external power supply operation.
The beneficial effects of the present invention are: invention uses working medium of the refrigerant as generating equipment, the absorption and release of heat
Speed is fast, and also low temperature heat user can heat while power generation, exhaust heat utilization effect.
Detailed description of the invention
Fig. 1 is the principle of the present invention figure.
In figure: 1. industrial exhaust heats, 2. evaporators, 3. compressors, 4. absorption heat pumps, 5. working medium generators, 6. heat users,
7, electric drive heat pump.
Specific embodiment
A kind of industrial afterheat recovery system of B-grade condensation, industrial exhaust heat 1, evaporator 2, compressor 3, absorption heat pump 4,
Working medium generator 5, heat user 6, electric drive heat pump 7；Waste heat is respectively delivered to evaporator 2, absorption type heat by the industrial exhaust heat 1
Pump 4, first part's waste heat are transported to the waste heat after evaporator for evaporating working medium, using 3 heating working medium of compressor, by working medium
It is transported to the workmanship of working medium generator 5, the working medium after workmanship still has certain temperature, is transported in absorption heat pump 4 as low temperature
Heat source, the remaining driving heat source as absorption heat pump 4 of second part, the high temperature heat drop temperature after driving absorption heat pump 4 is as electricity
The low-temperature heat source of heat pump 7 is driven, the combinations of sources of heat that two kinds of heat pumps obtain is used to be transported to heat user 6, heat for it, driving heat source
Again industrial exhaust heat 1 is transmitted back to after workmanship.
The present invention is not limited to the present embodiment, any equivalent concepts within the technical scope of the present disclosure or changes
Become, is classified as protection scope of the present invention.
